Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592416, here are decompositions:

5 + 31592411 = 31592416
47 + 31592369 = 31592416
59 + 31592357 = 31592416
197 + 31592219 = 31592416
257 + 31592159 = 31592416
293 + 31592123 = 31592416
419 + 31591997 = 31592416
503 + 31591913 = 31592416

Showing the first eight; more decompositions exist.
